Unipolar resistive switching in cobalt titanate thin films

We report giant resistive switching of an order of 104, long-time charge retention characteristics up to 104 s, non-overlapping SET and RESET voltages, ohmic in low resistance state (LRS) and space charge limited current (SCLC) mechanism in high resistance state (HRS) properties in polycrystalline perovskite Cobalt Titanate (CoTiO3 ~ CTO) thin films. Impedance spectroscopy study was carried out for both LRS and HRS states which illustrates that only bulk resistance changes after resistance switching, however, there is a small change (<10% which is in pF range) in the bulk capacitance value in both states. These results suggest that in LRS state current filaments break the capacitor in many small capacitors in a parallel configuration which in turn provides the same capacitance in both states even there was 90 degree changes in phase-angle and an order of change in the tangent loss.Comment: 7 pages, 4 figure

Effect of salinity stress on yield and quality parameters in flax (Linum usitatissimum L.)

Flax is one of the oldest utilitarian plants that have been grown for fibre as well as an oilseed crop. The species has been recognized as an excellent source of micronutrients, dietary fibre, protein, vitamin B1, lignan, and essential fatty acids (EFA), namely linoleic and α-linolenic acids. However, in spite of immense nutritional and industrial importance of the crop no work has been carried out on the effect of salinity induced by different salts on seed yield and quality traits in Linum usitatissimum. A high yielding germplasm line ‘Mukta’ was subjected to five concentrations (0 mM, 50 mM, 100 mM, 150 mM and 200 mM) of three salts viz. sodium chloride (NaCl), potassium chloride (KCl) and calcium chloride (CaCl2) for two seasons. Data were collected for seed yield along with different quality traits and a range of antioxidant enzymes. Seed yield decreased with rise in salt concentration and was minimum at 200 mM for all the salts. Chlorophyll a, chlorophyll b and carotenoid content continuously decreased with increase in salt concentration for all the salt treatments. Catalase and GST content increased with increase in salt concentration and was maximum at 200 mM

Genetic Association between Foliage Yield and Contributing Traits in Vegetable Chenopods: Implications for Genetic Improvement

A two-year study was conducted to evaluate the foliage yield potential in 13 germplasm lines of Chenopodium album for 3 successive cuttings. Correlations among foliage yield and its contributing traits, along with path analysis was also worked out. Foliage yield was maximum for C. album IC 107297, followed by C. album H.P. and C. album amaranticolor. The genotype × year interaction was non-significant for all the traits except stem diameter and moisture content. Leaf size, plant height and stem diameter showed significant positive correlation with foliage yield both at phenotypic and genotypic levels in all the cuttings. Chlorophyll a and chlorophyll b showed positive association with carotenoid content and negative association with ascorbic acid in all the cuttings as well as on pooled basis. Significant negative association was observed between leaves/plant and foliage yield at genotypic level in all the cuttings (Ist cutting: -0.472*; IInd cutting: -0.414*; IIIrd cutting: -0.480*) as well as on pooled basis (-0.591**). Protein content negatively affected foliage yield in all the cuttings. Fibre content had high negative value of direct path for pooled data but positively influenced foliage yield indirectly via leaves/plant, stem diameter, chlorophyll a, chlorophyll b and protein content. Ascorbic acid positively affected yield in Ist cutting as well as on pooled basis. Leaf size had high positive direct effect and significant positive association with foliage yield that indicates a true relationship between these traits. Leaf size also indirectly affected foliage yield in a positive direction through majority of other traits. Thus, direct selection for leaf size should be exercised to bring about improvement in foliage yield in C. album

Production, Marketing and Value Chain Analysis of Guava in Allahabad District of Uttar Pradesh, India

Allahabad region is best known for the guava. The study aims to observe the total production of guava under different size holding for that the farmers were divided into three size groups small, medium and large. The average total yield in different size groups was calculated. It was found that there were two main channels prevailing in the District. There were lots of problems involved in the VCA of guava viz. absence of producer\u27s association, guava wilt, long chain of middlemen and absence of VCA intelligence and financ

Seasonal variation of intestinal Tapeworms in Gallus gallus domesticus at Ahmednagar region

The present paper deals with the seasonal variation of tapeworms in Gallus gallus domesticus at Ahmednagar region, high prevalence of Raillietina parasite are occurred in winter season followed by summer season and low in rainy season. This type of results indicates that environment factors and feeding habitats are influencing that seasonality of parasitic infection either directly or indirectly

Pattern of adverse drug reactions reported at a tertiary care teaching hospital in northern India

Background: Adverse drug reactions (ADRs) are among the leading cause of morbidity and mortality in hospital setup. This study was conducted with the aim of understanding the pattern and occurrence of ADRs to minimize their risk and safeguard public health.Methods: This study is a retrospective analysis of pattern of ADRs reported at ADR monitoring centre (AMC) in a tertiary care hospital. A total of 207 spontaneous ADR reports collected over a period of 18 months were analysed for pattern and type of reactions, demographic profile of patients, organ system affected by ADRs, causative drugs, route of drug administration, severity of reaction, their outcome, management and causality assessment.Results: Most common age group affected by ADRs was 41-50 years with almost equal involvement of male and female gender. Cutaneous reactions involving skin like rashes and itching were most common ADRs. The most common causative drug for ADRs were antimicrobials agents like Penicillin and Cephalosporin group of antibiotics. Orally administered drugs were most commonly involved in causing ADRs. Most of the ADRs belonged to Type A category, were non-serious and moderate in severity. Most of the patients recovered from the ADRs on stopping the suspected drug. On assessing the causality, most of the ADRs were probable with the suspected drugs.Conclusions: Most of the patients recover from ADRs with appropriate and timely intervention, but it is important to understand the pattern and occurrence of ADRs for patient safety and this is possible only with an effective and robust pharmacovigilance system
